Özet:

 

 In this paper we establish some new compactness criteria for complete Riemannian manifolds with Bakry-\'Emery Ricci curvature bounded below. These results improve or generalize previous ones obtained by   H. Tadano [6], J. Wan [7], I.A. Kaboye and M. Bazanfar\'e  [3].  We also prove a volume comparison theorem for such manifolds.
